Can you imagine a video card without any flimsy plastic parts? Now you can because the NVIDIA GeForce GTX 690 will not be composed of any cheap plastics. A heavy duty dual vapor chamber cooling system relying on heavily nickel plated finstacks will sweat what little heat these GPUs pump out. A cast aluminum frame with trivalent chromium plating gives the card a unique look and tremendous rigidity. An injection molded magnesium fan housing adds to the formidable stiffness of the card. A brand new thixomolding process was used to get the required part precision.
The fan housing is made from injection molded magnesium alloy. Magnesium alloys are used throughout the automotive and aerospace industry (including the engines of the Bugatti Veyron and F-22 Raptor) for their light weight, heat dissipation and acoustic dampening properties - which is the same reason we use it in the GTX 690.
